So, according to HTC.com and Phonescoop.com, the radio for the Sprint version will have 1900mhz LTE, just as with the HTC Evo 4G LTE. Sprint is supposedly rolling out 800mhz LTE (former Nextel iDen) in the 2nd half of 2013. Question is, can the radio be modified via software to have 800mhz LTE, or is this a hardware issue?
Anyone know?
Thanks!

What a mess most of their customers will have, IMO stupid decision. Most people to use this network will need to replace their phones, and it means for you, that you have a decision to make on your LTE future, one which phone you buy or change provider, second option probably the best.
Please note that the Snapdragon 600 chipset does not have any modem support on chip, therefore additional hardware radios are added per requirement. HTC should have gone for the Snapdragon 800 which has a modem that supports LTE as well.
And in short, no you can't just change, it is hardware. However, towards the end of the year hopefully all phones will start to use the Qualcomm chipset announced yesterday which covers all bands worldwide.
HSPA/WCDMA:
Europe/Asia: 850/900/1900/2100 MHz
GSM/GPRS/EDGE:
850/900/1800/1900 MHz
LTE:
EU: 800/1800/2600 MHz
US (AT&T): 700/850/AWS/1900 MHz
US (TMO): 700/AWS MHz
US (Sprint): 1900 MHz
Asia: 1800/2600 Mhz
Re: Sprint iDen 800mhz -> Sprint CDMA/LTE 800mhz and the One
Ok thanks for the clarification that's what I was thinking. Perhaps Sprint will go ahead and pre-load the LTE radio for the former iDen 850 spectrum, and activate it with a firmware update. That's all I can hope for I guess.

Very interesting. Not sure what is going on, also not sure if HTC has any clue what is going on. There website is obviously wrong or not up to date. Still doesn't list 800MHz in US.
Looks like the One will only have Sprint band 25 LTE (1900). At least from the FCC figures.

SVDO is also missing, so no simultaneous 3G and voice. Understandably, though, with the LTE network increase.
Have gone from S1 to S2 with sprint, might go with HTC One instead of S4.
Does only one band of LTE on the phone mean there could be some towers that use the band not included in the phone, so I would only get 3g?

Do you have problems with Sprint now? are you using LTE currently?
Your LTE coverage will only be as good as how many 1900Mhz towers Sprint has around. If sprint doesn't have a tower in your phones range for LTE then you will only get 3G
If you travel a lot with roaming, then you will most likely want the AT&T model which covers most of greater America. If you get LTE while roaming will depend on Sprint and other Carriers agreements, otherwise yes your option will be 3G.
Thanks, I wasn't sure if their towers would have both bands or just 1, I wasn't sure why the phone only having 1900Mhz would matter.
I don't have an LTE phone, but I do have wimax coverage in Daytona, LTE is supposedly on the way. My work forces me to travel a lot, don't get to use 4g much anyway, I'm heavily dependent on roamcontrol, with a hacked PRL I make due with us cellular's 3g usually. When I am in Houston/Daytona I would like my LTE phone to have proper coverage though ;P

LTE coverage is great throughout Houston. It gets weak and sometimes drops to 3G when in buildings though.

Yes you are thinking correctly, however Sprint's 1900mhz is pretty comprehensive, in fact, I believe Sprint has more 1900mhz spectrum than any other carrier (hence why Sprint used to be 'Sprint PCS', referencing the PCS 1900mhz band), and far more 1900mhz spectrum than the old iDen 800mhz. You should not have any problems whatsoever.
Ill just be glad when they roll out 800mhz 3g..which this phone does have suport for. If they finally get around to upgrading the 3g here in Houston then I wont mind as much when the connection drops down. As such, the way it is right now, 3g is nigh on unusable, and sometimes so is 4g.

It has nothing to do with the modem. The One has a separate Qualcomm MDM9x15 modem which is not that much different than the modem that's integrated into the Snapdragon 800. It has plenty of ports which could handle another LTE band if one could be "fed" to it.
The issue is the front end RF stuff. Due to the uniqueness of the 800MHz LTE band that will be used by Sprint, it's difficult at this point to source the necessary antenna switches and transceivers and other front end RF components that will handle that specific 800Mhz LTE band.
My guess is that you won't see any ESMR800 LTE phones come out before Q3 or Q4 and it's also probably at least six months at this point before Sprint starts to deploy the technology commercially.

They are not going to roll-out EVDO on 800 MHz, only voice/1x, and a 5x5 LTE carrier.
That is not what I have heard from multiple Sprint reps about EVDO on the 800mhz. I was told, very recently in fact, that the voice/EVDO would be rolled out to the 800mhz, well before any LTE bands were activated in that spectrum. That Sprint was pushing for better penetration for voice and EVDO signals through the 800mhz spread, and that LTE would be focused on the 1900mhz for the time being.

According to this article:
http://www.lightreading.com/sprint/sprint-to-dial-800-for-lte-in-q4/240153521
"We expect to deploy LTE on 800MHz in the fourth quarter," said Steve Elfman, president of network operations and wholesale at Sprint on the call.
Nonetheless, Sprint is clearing the way for LTE integration with WiMax partner Clearwire. Hesse said he expects Clearwire's fast 4G service to start arriving late in the third quarter with "TD-LTE, multi-band devices."
With so many different chunks of frequency to support, Sprint will need these devices to switch between 2.5GHz, 800MHz and 1900MHz to get around the network.

That's not that unusual and really not that big of a deal for the the radios to handle in the upcoming devices.
In any case, working with multiple bands is fairly commonplace. Look at Verizon and AT&T for example which operate four different bands.

So good news for all Diamond euro owners in LA (and other places of course)...the tmobile network supports the 2100mhz band for 3G so no need for a US version!!
http://support.t-mobile.com/knowbase/root/public/tm23715.htm#7
Sorry if this is old news, but i just realized it =)
this is great if true?
T-Mobile devices use the 1700Mhz/2100Mhz frequency band (for 3G) and I thought Europe 3G devices use 900Mhz/2100Mhz. Could U clarify further...
you said it correct...tmobile does use 1700mhz/2100mhz, and the euro diamond supports 2100mhz which should work since tmobile will be using it...i spoke to a tmobile tier 2 rep, he confirmed it as well...
That can't be right. T-Mobile AWS 3G uses the 1700 MHz band for uplink and 2100 MHz for downlink. I doubt T-Mobile US set up aside any channels in the 2100 MHz band as uplink channels.
It's kind of academic, as I can't get 3G on T-Mobile USA using a Euro Diamond in NYC, where we've had 3G deployed for a few months now. I've never heard of anyone else doing it either. Oddly, there's a "UMTS(1700)" selection in the band settings in the phone control panel, but if I try selecting that, it just jumps back to using T-Mobile's normal PCS band with EDGE for data.
If that tier 2 tech can get you onto AWS 3G with your Diamond, definitely let us all know about it, but don't get your hopes up too high.

As I understand it, if a phone says it supports 2100 it is referring to the UMTS Band 1 used in Europe which is 1920-1980MHz Uplink & 2110-2170Mhz Downlink (see UMTS Frequency Bands - Wikipedia). The 1700AWS Band (UMTS Band 4) uses 1710-1755MHz Uplink and 2110-2155MHz Downlink. So, while they do overlap some they are not identical (A Visual Guide to AWS - PhoneScoop)
So, I don't believe that a phone with 2100 EU support will work with T-Mobile 3G because it doesn't support the 'right' 2100 nor the 1700. Likewise, I don't believe that a phone with 1700 support will work for 2100 EU.
If you want to get technical the "US" Diamond won't work for 3g on T-Mobile either. The 3g band is only for 850/1900. (so i guess we're screwed either way) I'm in Salt Lake City and I don't believe Utah is slated to get 3g until 2009 at this point. I bought the diamond knowing full well that 3g was going to be a slim possibility on this phone. However, a user with a DIAM100 is claming that he's been getting 3g service on T-Mobile in NJ. He said that he'd post screenshots.. I don't know if he's done that or not. I guess all we can do is wait and see.

I have the USA sold "quad band" euro diamond distributed by htc USA. This is essentially re-flashed euro diamond hardware sold to support american networks, not the 850/1900 newest USA 3G diamond compatable with AT&T. I have looked into this issue and also talked to T-mobile and there seems to be alot of confusion regarding T-mobile's AWS USA 3G network (or maybe they have simply confused me). Here is what I have found out: Assuming they are correct, they are telling me 3G voice for T-mobile usa runs in both the 1700 AND 1900 mhz band, and therefore my euro diamond shoud be supported at 1900mhz for voice 3g support. This 1900mhz is part of the "quad band" voice radio hardware on the euro diamond. Data (AWS 3G for USA) "HSDPA" , which T-mobile has not yet released, runs in the 2100mhz bandwidth, and Data AWS "HSUPA 3g" runs in the 1700mhz bandwidth. Therefore my hardware would not support HSUPA @ 1700mhz, but would support the HSDPA @ 2100mhz. As to the idea that euro bandwidths are different than USA bandwidths, well apparently they are. For example "2100mhz" networks in europe might be actually using 2110mhz-2170mhz, whereas in the USA T-mobile's network may use 2100-2140mhz actual bands. However because these are close and still in the 2100mhz band, there should still be compatability with 2100mhz hardware radios regardless of networks varying the bandwidth slightly.
Of course this may be too optimistic, but it would be very cool if true and I am hoping for the best .

Unfortunately, they've provided you some bad information. Each frequency band/range has a pair of uplink and downlink frequencies - you can't use one without the other - you have to use both. Generally, the uplink and downlink frequencies are relatively close to each other however, the 1700 AWS band has uplink and downlink spread quite a distance apart. Uplink is in the 1700MHz range, downlink is in the 2100MHz range and both have to be used. In the US, 1700 & 2100 is essentially one band.
1900MHz (the PCS band) isn't 3G for T-Mobile (although they technically could put it there at some point.) Right now, 1900MHz for T-Mobile is EDGE voice and data. Most other carriers do have 3G on the 1900MHz band, T-Mobile just doesn't have enough spectrum available in that band.
In short: A phone that supports UMTS 2100 will not work for T-Mobile US 3G. A phone that supports AWS/UMTS 1700 will work for T-Mobile US 3G but not for European 2100 3G. (And 1900MHz PCS will give you traditional EDGE on T-Mobile US.)

So I've done my best to scour the seemingly millions of posts on this site, and I've found lots of useful info. What I really need is a "ROM" or "patch" or whatever you'd call it that will get my X1i onto AT&T's 3G network. I live in the Florida Keys where we have both 3G and Edge networks. For what ever reason my phone will always get on the Edge. While in Atlanta in May I was all over their 3G in certain areas. So I know my phone will use 3G, just not where I live. Any help would greatly be appreciated.
I am looking for this fix too. Hopefully in a ROM form.
I have the X1i but my carrier (Rogers/Fido) would work 3G only if I ha the X1a, would the X1a ROM be able to fix that?
No, ROMs won't control or overcome the limitations of the the physical hardware.. if you have an X1i (900/1900/2100) it will not be able to work no matter what in areas that require the 850 Mhz band.
AT&T has some 1900 Mhz 3G areas, but it is spotty as best. Canada used to have some 1900 Mhz 3G test areas in GTA, but Rogers has switched to 850 Mhz/1900 Mhz dual bands almost completely.
You're kind of out of luck if you have an X1i in North America.

Yea, it just depends on the area. In NC, ATT 3G is deployed on 1900MHz, but in other states where ATT has 850MHz, they may deploy 3G on the 850MHz band.

Have you found a fix to this yet?
If you have updated to the latest and greatest @ R3....try reflashing the device to the original R1....when I flashed to R3 edge was my primary signal...has to do with what they changed in the rilphone.dll...

As lazyjai said, you can't get an X1i on ATT 3G in north america. It's not a software thing, its a hardware thing. The X1i does not have the parts it would need to run on 3G in america. Thats why the X1a was made with american 3G parts. X1american (X1a) vs. X1international (X1i). So, there is no way to make it run ATT 3G in america (This includes roms, cabs, etc...).
Incorrect....
◦GSM/GPRS/EDGE 850/900/1800/1900
◦UMTS/HSDPA/HSUPA 900/1700/1900/2100 MHz
◦UMTS/HSDPA/HSUPA 850/1700/1900/2100 MHz
X1i will work on these frequencies....so if the 3g or higher signal is available in your area it will use it...if not then you are stuck on the edge frequency...I know in Orlando/surrounding area's they are upgrading the network so it may be readily available shortly....

Guys there is NO fix for this.
AT&T has deployed their 3G network in the US on the 850MHz and 1900MHz bands. Depending on the area, both of these 3G bands, or either one maybe deployed. I have an X1a. In NC, AT&T only has a license for the 1900MHz band, for example. When I was in Baltimore, I was using the 850MHz 3G band.
The X1a support 3G frequency bands - 850MHz/1900MHz/2100MHz - ie. there is a hardware power amplifier for these three bands ONLY.
X1i - 900MHz/1900MHz/2100MHz - ie. there is a hardware power amplifier for these three bands ONLY.
Physical hardware limitation.
If your area has 850MHz 3G and you are using a X1i, you will NOT or EVER get 3G on the 850MHz band.
This has been discussed ad nauseum. If there was a fix, I'm sure the brilliant minds at XDA would have found it already.

Wrong. Neither supports 1700MHz on UMTS/HSPA.
Both do quadband GSM/GPRS/EDGE 850/900/1800/1900

You might just be in a refarm area without LTE.

It most likely means you are not in a LTE area. 3G is UMTS and H HSPA+. I am sure if it was LTE you would see LTE or 4G on the screen. Run speed test and go to the settings menu and see what connection you are getting. It will tell you if it is one of the top 3. I do not think LTE is in Chicago yet for T-Mo. Also T-Mo changes the 3G/H with a 4G logo to make you think the phone is 100% of the time in 4G mode, it isn't. during sleep/deep sleep the phone goes into 3G (UMTS) to save battery.
Also make sure you have a LTE-capable SIM from T-mo.

H is 4G. It's just the icon the device displays. Some display 4G an some H but they are the same speeds.

Tmobile's LTE is Band IV 1700, no?
The unlocked developer's edition DOES NOT support that signal.
Am I mistaken?
Furthermore, if I'm not mistaken about this too, I believe the dev edition only supports Tmobile's HSPA 21 MB/s. It doesn't even support HSPA+ 42 MB/s.
Please correct me if I'm wrong? What will the refarming do?

It seems to be true that the dev edition will only do 21Mb/s and only where 1900 has been refarmed in regards to HSPA. It DOES support T-Mobile LTE though which is listed as AWS (1700/2100 bands) in the tech specs.

I thought Tmobile LTE is only 1700, which isn't listed from HTC's website of the Dev edition:
Compatible on these frequencies:
HSPA/WCDMA: 850/1900/2100 MHz
GSM/GPRS/EDGE: 850/900/1800/1900 MHz
LTE: 700/850/AWS/1900 MHz (US)
But you also said 2100 which is listed. Is 2100 also LTE? I thought 2100 was only HSPA+? If it is LTE, why isn't it in the LTE category from the website?
All genuine questions. I'm confused.

I won't claim to be an expert on radio frequencies but it I would propose that there's nothing stopping a radio from being capable of picking up two different formats at the same frequency (at separate times). It just depends which format is broadcast at a given frequency in the area.

AWS is 1700/2100. TMO uses 1700 for up or down ( i can remember which) and 2100 for the other. 3G and HSPA wont work unless you are in a refarmed area on the dev edition. As someone said previously, "H" should be LTE since Chicago and suburbs have both LTE and have been refarmed. I have a dev edition and will be switching to TMO next month, and I live in Chicago as well. Im hoping that someone will get AWS frequencies unlocked on the dev edition. In the mean time:
OP try the following-
Flash a tmo stock rom and see what it gives you for signal. It should show LTE instead of H, but no difference in speed.
I will return it and get tmo version

Do you mean AWS 1900? So that's 4G LTE?
Then what's the big fuss about "Band IV 1700" LTE? Is that a different sort of LTE? Better? Worse?
Appreciate you clarifying. I'm confused.
It will work. There's various screenshots of it working. Also a HTC rep clarified this not too long ago on Twitter.

onthecouchagain, you gotta actually read man. AWS IS T-Mobile LTE. AWS 1900 doesn't mean anything. Go back and read the specs for the developer edition, it says LTE support bands are 700/850/AWS/1900. See how the third item there is AWS. AWS is the band (or more specifically set of bands) that run T-Mobile LTE. And as numerous people on this thread have already reported, the developer edition works on T-Mobile LTE. The only thing the developer edition doesn't support is UTMS 1700, which means if you don't live in a refarmed 1900 MHZ area OR you don't live in an area where T-Mobile has LTE live, then you'll only get edge speeds and won't pick up HSPA+ on the 1700 mhz band.
Hello everyone
I have found one tower in the Houston area that is pumping out spark speeds. 290 just past Hollister near the panera bread I got download speeds of over 65mbps!
I have to say at first I laughing at spark when they said 100mbps or more..I figured oh great this will take another 9 years to see it but I'm sure if it was the middle of the night and not during rush hour I would have gotten over 100mbps easily..
Let's post any other spark tower locations if you guys find them

An update is required but I figured out (by a miracle mistake) that enabling the bands and then cycling PRL update and profile update would let you connect to B41... that is until you restart your phone and have to do another PRL + profile update.
So yeah... spark update is still required.

after enabling the bands if you do a profile update it will change the priorities of the bands but should still leave all bands enabled. sprint never touches the ota's so a software update wouldnt be able to change it id assume only a profile update will change it.. prl should only change the prl not your engineering profile settings.
test it out.. enable the other 2 bands and find spark tower ill post a pic after work of the towers and attachments

Sprint LTE maps... I laugh at them and you should too. Overstates coverage for everything though it is getting a little bit more accurate with LTE 800 being deployed but it's still a crapshoot. Look at the 1x map and then decrease it a little bit and you'll have the LTE coverage map as PCS LTE is always weaker than 1xRTT 1900.
I, and a very few select others over @ s4gru.com, have access to to a very recent engineering map from clearwire that has what sites are live as part of the Phase 1 TDD-LTE deployment and deployment schedules (& time frames) for some markets.
Some of us have been actually running around Phase 1 sites (Phase 2A {1st half 2014} are just beginning) getting engineering screens. In fact I just went to another one just a 2 hours ago...

No one actually is sure what exactly the turbo area is. We assume it's just areas where the actual Band 41 sites got upgraded backhaul to spit out the 50-60 mbps peak speeds. Many sites are still running on old clearwire wimax backhaul which tops at 10-20 mbps per sector.

Hmmm Interesting.. Thanks for the info I have no clue what turbo is.. Sounds very 80sish haha.
Im convinced that at after hours that cell site would push much more than 70mbps like I got earlier.. All the office buildings nearby including my office cause some congestion.. I just still have a hard time believing 1.9 has that throughput alone
Only site I've found around that has those speeds and not sure it matters but I'm running .15 modem

I confirmed using the engineering screen that that tower mentioned in the op is putting out 41
My phone was connected to band 41 and pushing 70mbps
I just came off a 10 day roadtrip over the southeast, including 4 days in the Tampa market. I tried prl updates with the suggested settings, but never could get Spark like speeds or even connect on band 41. Funny think was that the fastest Sprint speeds I found were at my house in the central Arkansas area. Coverage is really bad here on Sprint, but I live next to a tower getting 32/8 on 1900.
I have found a way to consistently connect to band 41 lte aka spark. It is risky though. By flashing the .15 radio and enabling all the bands with band 41 as the first priority you can connect much more easily. The downfall is that on sites without an e/CSFB upgrade which tells your phone to fall back to 3g for a call, it won't kick you off lte so you could be unknowingly without service but you'll have LTE data. More can be found on this at s4gru but I thought I'd let you guys know about the .15 baseband.
Can someone find which towers are spark active in Wichita Kansas?

This is exactly how I got the 41 band near work. .15 modem with all bands enabled priority 0 0 1.
Fortunately there are less and less towers not ecsfb
So after the denim update, AWS (aka 1700/2100 or LTE Band 4) support for the icon(929) became available, and because of this I purchased the Icon and I love it. However I live in Canada and have a month to month plan with Mobilicity. I guess I didn't do my research well enough (I'd like to think the internet was a bit misleading but....i guess its matter of perspective). Mobilicity solely rely on the AWS band frequency. They don't offer LTE but instead use HSPA . I knew that already but I figured that since AWS was supported I could receive HSPA signal over the 4G radio but nope I was wrong.
So I guess there are enough distinct differences between HSPA on AWS and LTE on AWS enough for them to be not cross compatible? Is this a hardware "issue" or a firmware/software one that I could do something about? Is it possible to enable 2G/3G/HSPA over the 4G radio? Or maybe I can get it to work by setting the APN correctly? I looked at some phones specs over on GSMArena which do offer HSPA + LTE support over AWS, I really want to say that it seems unlikely that 2 or more pieces of hardware are required to offer 2 services on what is essentially the same frequency.
